Background: Mucosal-associated invariant T(MAIT) cells are systemically depleted in human immunodeficiency virus type 1(HIV-1) infected patients and are not replenished even after successful combined antiretroviral therapy(cART).This study aimed to identify the mechanism underlying MAIT cell ***: In the present study, we applied flow cytometry, single-cell RNA sequencing and immunohistochemical staining to evaluate the characteristics of pyroptotic MAIT cells in a total of 127 HIV-1 infected individuals, including 69 treatment-naive patients, 28 complete responders, 15 immunological non-responders, and 15 elite controllers, at the Fifth Medical Center of Chinese PLA General Hospital, Beijing, ***: Single-cell transcriptomic profiles revealed that circulating MAIT cells from HIV-1 infected subjects were highly activated, with upregulation of pyroptosis-related genes. Further analysis revealed that increased frequencies of pyroptotic MAIT cells correlated with markers of systemic T-cell activation, microbial translocation, and intestinal damage in cART-naive patients and poor CD4+ T-cell recovery in long-term cART patients. Immunohistochemical staining revealed that MAIT cells in the gut mucosa of HIV-1 infected patients exhibited a strong active gasdermin-D(GSDMD, marker of pyroptosis) signal near the cavity side, suggesting that these MAIT cells underwent active pyroptosis in the colorectal mucosa. Increased levels of the proinflammatory cytokines interleukin-12(IL-12) and IL-18 were observed in HIV-1 infected patients. In addition, activated MAIT cells exhibited an increased pyroptotic phenotype after being triggered by HIV-1 virions, T-cell receptor signals, IL-12 plus IL-18, and combinations of these factors, in ***: Activation-induced MAIT cell pyroptosis contributes to the loss of MAIT cells in HIV-1 infected patients,which could potentiate disease progression and poor immune reconstitution.

像木星和土星这样的冷巨行星对类地行星的形成和宜居性起到了关键作用,因此,对像太阳系这样具有多个冷巨行星的系统的搜寻具有重要意义.kepler以及TESS (Transiting Exoplanet Survey Satellite)太空望远镜成功地通过凌星的方法发现了大量短周期行星,然而这些巡天项目的观测基线不足以发现更长周期的行星.为此,天语计划将部署两台1.望远镜(天语一号和天语二号),用于结合天语和其他计划的数据通过凌星法来发现冷巨行星及其他行星,并最终发现类太阳系.天语一号具有约1.平方度的视场以及高速CMOS (complementary metal-oxide-semiconductor)科学相机,将对超过1.00万颗恒星每小时进行一次高精度测光采样,并通过天语二号的多波段测光、光谱仪以及高分辨率成像对天语一号发现的候选行星进行确认.天语望远镜将放置于海拔约4000m的中国青海冷湖,是目前中国境内最好观测台址之一.天语对亮于1.等星的测光精度为0.1.,对亮于1.等星的测光精度优于1.,天语预计在5yr内将在类太阳周期发现超过300颗凌星行星,其中包括约1.颗冷巨行星.基于系统轨道共面以及孪生地球发生率为1.%的假设,天语预计将发现1.2个类太阳系,并可被未来的地球2.0计划所证实.此外,天语还将通过多种巡天观测模式测量从亚秒到周时标的光变,探测不同时标的时域现象,包括超新星早期光变、稀有变星和双星、潮汐瓦解事件、Be星、彗星活动以及系外小行星等.这些发现不仅将深化我们对宇宙的理解,还将为公众科学和科普提供重要平台.

目的通过手动分割和自动分割得出正常人脑的总体积、脑脊液体积、灰质白质体积,分析不同性别的差异和随年龄变化的模式,同时给出可以得到较优结果的软件和参数。方法通过软件自动分割得到粗略的脑掩模后进行手动精细分割,然后用FSL-FAST分为灰质、白质和脑脊液,最后用SPSS 25. 0。软件进行统计学分析。结果中国正常成人脑总体积约1.63. 24 ml,男性脑总体积(1.1.. 84 ml)大于女性脑总体积(1.73. 1. ml),差异有统计学意义。不同年龄的脑总体积、灰质、白质和脑内脑脊液体积差异有显著性。灰质白质比与年龄无相关性。男性脑总体积、灰质、白质体积均大于女性,三者随年龄增大而降低的模式相似。女性脑总体积、灰质、白质体积随年龄变化的模式相似,在约50岁时达到最大值,随后体积逐渐减小。结论不同性别人脑体积及灰质、白质、脑脊液体积随年龄变化作为鉴别正常脑体积变化与疾病导致的脑体积变化的依据。
